From c3982f5bddf56bbc96d838ea35540eae81504bb3 Mon Sep 17 00:00:00 2001 From: Jozef Lawrynowicz <jozef.l@mittosystems.com> Date: Fri, 16 Nov 2018 23:53:30 +0000 Subject: [PATCH 08/22] Backport: ICE: segmentation fault with patchable_function_entry attribute for msp430-elf -mlarge) 2021-10-07 Giuliano Belinassi <gbelinassi@suse.de> Backport from mainline 2018-11-16 Jozef Lawrynowicz <jozef.l@mittosystems.com> PR target/87927 * target-def.h: Initialize TARGET_ASM_{,UN}ALIGNED_P{S,D,T}I_OP. Add them to the TARGET_ASM_{,UN}ALIGNED_INT_OP structs. * target.def: Enumerate TARGET_ASM_{,UN}ALIGNED_P{S,D,T}I_OP in the byte_op hook. * target.h: Add psi, pdi, pti to struct asm_int_op definition. * targhooks.c (default_print_patchable_function_entry): Assert asm_int_op does not return a NULL string. * varasm.c (integer_asm_op): Return the op for a partial int type when the requested size does not correspond to an integer type. * config/msp430/msp430.c: Initialize TARGET_ASM_{,UN}ALIGNED_PSI_OP. * doc/tm.texi: Regenerate. --- gcc/config/msp430/msp430.c | 5 +++++ gcc/doc/tm.texi | 6 ++++++ gcc/target-def.h | 15 +++++++++++++++ gcc/target.def | 6 ++++++ gcc/target.h | 3 +++ gcc/targhooks.c | 4 +++- gcc/varasm.c | 14 ++++++++++++++ 7 files changed, 52 insertions(+), 1 deletion(-) diff --git a/gcc/config/msp430/msp430.c b/gcc/config/msp430/msp430.c index c1f0d5b0026..3ad552d9e94 100644 --- a/gcc/config/msp430/msp430.c +++ b/gcc/config/msp430/msp430.c @@ -3391,6 +3391,11 @@ msp430_print_operand_raw (FILE * file, rtx op) } } +#undef TARGET_ASM_ALIGNED_PSI_OP +#define TARGET_ASM_ALIGNED_PSI_OP "\t.long\t" +#undef TARGET_ASM_UNALIGNED_PSI_OP +#define TARGET_ASM_UNALIGNED_PSI_OP TARGET_ASM_ALIGNED_PSI_OP + #undef TARGET_PRINT_OPERAND_ADDRESS #define TARGET_PRINT_OPERAND_ADDRESS msp430_print_operand_addr diff --git a/gcc/doc/tm.texi b/gcc/doc/tm.texi index b4456f7cd40..cb9fabb4295 100644 --- a/gcc/doc/tm.texi +++ b/gcc/doc/tm.texi @@ -7798,12 +7798,18 @@ hook. @deftypevr {Target Hook} {const char *} TARGET_ASM_BYTE_OP @deftypevrx {Target Hook} {const char *} TARGET_ASM_ALIGNED_HI_OP +@deftypevrx {Target Hook} {const char *} TARGET_ASM_ALIGNED_PSI_OP @deftypevrx {Target Hook} {const char *} TARGET_ASM_ALIGNED_SI_OP +@deftypevrx {Target Hook} {const char *} TARGET_ASM_ALIGNED_PDI_OP @deftypevrx {Target Hook} {const char *} TARGET_ASM_ALIGNED_DI_OP +@deftypevrx {Target Hook} {const char *} TARGET_ASM_ALIGNED_PTI_OP @deftypevrx {Target Hook} {const char *} TARGET_ASM_ALIGNED_TI_OP @deftypevrx {Target Hook} {const char *} TARGET_ASM_UNALIGNED_HI_OP +@deftypevrx {Target Hook} {const char *} TARGET_ASM_UNALIGNED_PSI_OP @deftypevrx {Target Hook} {const char *} TARGET_ASM_UNALIGNED_SI_OP +@deftypevrx {Target Hook} {const char *} TARGET_ASM_UNALIGNED_PDI_OP @deftypevrx {Target Hook} {const char *} TARGET_ASM_UNALIGNED_DI_OP +@deftypevrx {Target Hook} {const char *} TARGET_ASM_UNALIGNED_PTI_OP @deftypevrx {Target Hook} {const char *} TARGET_ASM_UNALIGNED_TI_OP These hooks specify assembly directives for creating certain kinds of integer object.
